FLUID-FUEL BURNER.

Specification of Letters Patent- Patented A11 3, 1915.

Application filed October 28, 1914. Serial No. 868,958.

To all whom it may concern:

Be it known that I, HANS T. PETERSEN, citizen of the United States,residing at Seattle, in the county of King and State of VTashington,have invented a certain new and useful Improvement in Fluid-FuelBurners, of which the following is a specification.

My invention relates to improvements in burners for burning fluid fuelin boiler furnaces, and in the fire-boxes of cooking stoves and heatingstoves, and the object of my invention is to provide a burner that shallbe simple in its plan of construction, reliable and eflicient inoperation and that shall be adapted to burn both high and low grades offluid fuel, as, for instance, gasoline, kerosene oil and crude petroleumas well as different gases. I attain such objects by devices illustratedin the accompanying drawings wherein Figure 1 is a view in longitudinalmidsection of a burner embodying my inven tion; Fig. 2 is a view of thesame in crosssection on broken line 00, w of Fig. 1; Fig. 3 is a view ofthe same, on a reduced scale, in cross-section on broken line y, y ofFig. 1, and Fig. 4 illustrates a modified form of a detail inlongitudinal mid-section of the same.

Referring to the drawings, throughout which like reference numeralsindicate like parts, a hollow cylindrically formed body portion 5, ofcast metal, which is provided on its lower end portion with oppositelyprojecting bosses 6 and 7, respectively, has its interior hollow spacedivided by a partition 8 to form two chambers 9 and 10 a fluid fuelsupply pipe 11 is disposed to screw into the boss 7 to communicate withthe chamber 10 and a pipe 12, for steam or compressed air, is disposedto screw into the boss 6, through which pipe 12 steam or compressed airmay be admitted into the chamber 9. The upper end wall of the chamber 9is provided with a slotted opening 13 which extends crosswise in a planeparallel with and adjacent to the partition 8, through which a thinsheet of steam or compressed air may be emitted from the chamber 9 in adirection parallel with the axis of the body portion 5.

The chamber 10 extends upwardly for a slightly greater distance than thechamber 9 whereby the inner side of its upper end wall is higher thanthe outer side of the upper end wall of the chamber 9 and a thin slottedopening 14 is disposed to extend outwardly from the top of the chamber10 in a horizontal plane that intersects the vertical plane of the slot13, thus fluid fuel under pressure may flow from the chamber 10 throughthe slotted opening 11 in the form of a thin sheet-like'jet immediatelyto impinge upon the side of the sheet-like jet of compressed air orsteam that may be flowing upwardly in a vertical direction from the slot13 thus to mix with such compressed air or steam and be carried upwardthereby in the form of a combustible mixture.

The upper and outer portion of the upper end wall of the chamber 10 isenlarged and formed to provide a screw-threaded socket 15. The upperpart of the body portion 5 is provided with an external screw-thread andscrewed thereon is a larger end of a reducer coupling 16 into whosesmaller end is screwed the lower end of a pipe 17 upon whose upper endis screwed a burner tip 18 and concentrically disposed within the pipe17 is a rod 19 the lower end of which is screwed into the screw-threadedsocket 15, while upon its upper end is mounted a plurality of radiallyslotted disks 20 of such diameter as will cause their peripheries toengage with the inner surface of the pipe 17. The radial slots of eachof adjacent ones of said disks 20 are disposed in a staggered relationwith each other thus to serve as a baflle to mix more thoroughly thefluid fuel and the steam or air as such mixture flows toward the burnertip 18.

Fig. 3 illustrates more clearly by full lines and dotted lines therelative positions of the radial slots of adjacent ones of disks 20.

In Fig. 4 I have shown a projecting ridge 21 disposed on the exteriorsurface of the upper end wall of the chamber 9 adjacent to and parallelwith the slot 13, which projecting ridge 21 may serve to deflect thefluid fuel as it issues in a sheet-like jet from the slotted opening14:. Such ridge 21 may be advantageously employed when heavy low gradeoil is used as a fuel but is unnecessary in cases where more volatileoils or gases are used as a fuel.

The operation of my burner is as follows: Fluid fuel is admitted intothe chamber 10 through the pipe 11 from a valve-controlled source ofsupply not shown and air under pressure, or steam, is admitted into thechamber 9 through the pipe 12, the fluid fuel passing out of the chamber10' through 17 and the radial slots of the disksQO and thence throughand out of the burner tip 18 to-be ignited at-the point of combustion.
